latex-builder 0.0.13

A tool for building LaTeX documents with Git integration and diff generation

LaTeX Builder

A Python tool for building LaTeX documents with Git version management and automatic diff generation.

Features

• Git Integration: Automatic detection of current commit, branch, and tag information
• LaTeX Compilation: Complete compilation workflow using XeLaTeX and BibTeX
• Diff Generation: Create visual differences between Git versions using latexdiff
• Version Management: Generate version information files for LaTeX documents
• Clear Logging: Beautiful command-line interface with clear progress indicators
• GoReleaser-like Versioning: Smart version naming based on Git tags and working tree status

Version Naming Logic

The tool uses GoReleaser-like version naming:

• Tag commits: {tag}-{commit} (e.g., v1.2.3-a1b2c3d)
• Non-tag commits: {next_version}-snapshot-{commit} (e.g., v1.2.4-snapshot-a1b2c3d)
• Dirty working tree: {version}-dirty-{commit} (e.g., v1.2.4-dirty-a1b2c3d)

Where {next_version} is the patch-bumped version of the latest semantic version tag.

Usage

Command Line

# Basic usage (in Git repository containing main.tex)
pipx run latex-builder

# Specify LaTeX file
pipx run latex-builder -t document.tex

# Specify output directory
pipx run latex-builder -o build_output

# Enable verbose output
pipx run latex-builder -v

# Full options
pipx run latex-builder -t main.tex -r misc/revision.tex -o output -b build -v

Generate Only revision.tex

# Generate revision.tex only (no build or diff)
pipx run latex-builder revision

# Specify output path for revision.tex
pipx run latex-builder revision --revision-file misc/revision.tex

Python API

from latex_builder import Config, LatexDiffTool
from pathlib import Path

# Create configuration
config = Config(
    tex_file="main.tex",
    revision_path="misc/revision.tex",
    output_folder=Path("output"),
    build_dir=Path("build"),
    verbose=True
)

# Run tool
tool = LatexDiffTool(config)
exit_code = tool.run()

Configuration Options

• tex_file: Main LaTeX file to compile (default: "main.tex")
• revision_path: Path to revision.tex file (default: "variables/revision.tex")
• verbose: Enable debug logging (default: False)
• output_folder: Output files directory (default: "output")
• build_dir: Temporary build files directory (default: "build")

Output Files

The tool generates the following output files:

• Current Version PDF: {version-name}.pdf
• Diff Files:
  • LaTeX Source: {compare-version}-vs-{current-version}.tex
  • PDF Document: {compare-version}-vs-{current-version}.pdf
• Metadata: metadata.json containing version information
• Version File: revision.tex containing version macros for LaTeX

Examples:

• v1.2.3-a1b2c3d-20241130091545-vs-v1.2.4-snapshot-e4f5g6h-20241201143022.tex
• v1.2.4-snapshot-a1b2c3d-dirty-20241201143022-vs-v1.2.5-e4f5g6h-20241202120000.pdf

The timestamp format is YYYYMMDDHHMMSS in UTC timezone. Version naming follows the pattern:

• Tag versions: {tag}-{commit}-{timestamp}
• Non-tag versions: {next_version}-snapshot-{commit}-{timestamp}
• Dirty versions: {version}-{commit}-dirty-{timestamp}
• Dirty snapshots: {next_version}-snapshot-{commit}-dirty-{timestamp}

Requirements

• Python 3.11+
• Git repository
• LaTeX installation including:
  • XeLaTeX
  • BibTeX
  • latexdiff

Example

# In a Git repository containing LaTeX project
cd my-latex-project

# Install package
uv pip install -e /path/to/latex-builder

# Build current version and generate diffs
uv run latex-builder -v

This will:

1. Analyze current Git state
2. Generate version information files
3. Compile current version PDF
4. Generate diff documents with previous commit and previous tag
5. Output all files to output/ directory

Architecture

The package uses a modular architecture with clear separation of concerns:

• CLI Layer: Handles command line interaction
• Core Logic: Git operations, LaTeX processing, diff generation
• Configuration: Centralized settings management
• Utilities: Shared functionality for logging and command execution

Each module can be tested independently, following Python best practices.
